Answer:

x =22

Step-by-step explanation:

ABCD is a parallelogram. In parallelogram, adjacent angles are supplementary.

∠B +∠C = 180

4x + 12 + 3x + 14 = 180

Combine like terms

4x +3x + 12+ 14 = 180

7x + 26 = 180 {Subtract 26 from both sides}

7x = 180 - 26

7x = 154 {Divide both sides by 7}

x = 154/7

x = 22

The conclusion that is valid based on the result of the test would be : A. Her students on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated

we can see in the statement that the average student only need about 25 minutes to take the quiz

hope this helps

An amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ

pshichka [43]

I found a missing question online. What is the magnitude of the angular displacement of the ride in radians between times t=0 and t= t1?
We can imagine our ride traveling from the starting point A to some point B (at t=1s).
We can find the angle of both points, and when we subtract them we get angular displacement.
 $A: \theta(0)=a\\
B: \theta(1)=a+b(1)^2-c(1)^3=a+b-c$
Our angular displacement is:
 $\Delta\theta=\theta(1)-\theta(0)=a+b-c-a=b-c=0.85-0.035=0.815 rad$

Please Help! :) Solve for X. The polygons in each pair are similar.

Diano4ka-milaya [45]

Answer:

x=2.65

Step-by-step explanation:

First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

$4x-5*2.5=14$

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

$4x-5=5.6$

Next, add 5 to both sides:

$4x=10.6$

Then divide both sides by 4:

$x=2.65$
